The Birch Natural Down Duvet Insert is filled with a blend of 70% white down and 30% natural wool. The down is Responsible Down Standard (RDS) certified to ensure humane and ethical sourcing, while the wool provides exceptional breathability and comfort without adding unnecessary weight.
Each duvet insert cover is made with breathable organic cotton that’s soft and cool to the touch. Organic cotton naturally wicks away moisture, keeping you cool and comfortable throughout the night.
For lasting quality, the duvet features baffle box stitching for loft and even fill distribution, along with double-stitched edges and German piping for enhanced durability.
